Well, it's stuff not related to our RDMA userspace API (which _is_ Verbs, not counting for the complete crackpot abuse in usnic), but very device specific. The stuff the intel driver are doing isn't pretty, but unfortunately not unusual either - lots of SCSI or network driver have ioctls like that. Now we could argue if the ioctls should be one the main node (uverbs) or the a driver private chardev, or not exist at all and people will have to patch the driver with some vendor version if they really need it. Examples for either of these choices exist in the tree. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
